‎2017-2018学年高一下学期期末考试备考满分冲刺专题 专题六 必修4重点语法 讲解部分 要点一:集合名词与主谓一致 ‎1. (2017·江苏) The publication of Great Expectations, which ____________ both widely reviewed and highly praised, strengthened Dickens, status as a leading novelist.‎ A. is B. are C. was D. were ‎【参考答案】C ‎【试题解析】考查主谓一致。本句是包含定语从句的复合句,先行词是Great Expectations是书名,看作单数,所以定语从句的谓语也要使用单数形式;根据"strengthened"可知,"被广泛阅读和得到高度评价"发生在过去,故选C。‎ ‎2. (2015·湖南) It is important to remember that success ___________ a sum of small efforts made each day and often ___________ years to achieve.‎ A. is; takes B. are; takes C. are; take D. is; take ‎【参考答案】A ‎【名师点睛】‎ 本题旨在考查主谓一致原则,要求学生掌握这一原则及其用法,确定句子主语的单复数,不要受其他干扰项干扰而答错。主谓一致是指:(1) 语法形式上要一致,即单复数形式与谓语要一致。(2) 意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。 (3) 就近原则,即谓语动词的单复数形式取决于最靠近它的主语, 一般来说,主语为不可数名词,谓语用单数;主语为可数名词复数,谓语用复数。(4)就远原则,即谓语动词的单复形式取决于离它最远的主语, 一般来说,主语为不可数名词,谓语用单数,主语为可数名词复数,谓语用复数。‎ ‎3. (2013·湖南) The university estimates that living expenses for international ‎ students ___________ around $8,450 a year, which ___________ a burden for some of them.‎ ‎ A. are; is B. are; are C. is; are D. is; is ‎【参考答案】A ‎【试题解析】考查主谓一致。句意:那所大学估计,对国际学生来说,一年的生活开销大约是8450美元,这对他们中某些学生来说是一个负担。第一空的主语是living expenses,是复数,因此谓语动词用复数;第二空的主语是which,指代的是前面living expenses...a year整个句子,因此谓语动词用单数。‎ ‎4. (2016·浙江) He would ask who we was and pretend not to knowing us.(改错)‎ ‎ ______________________________________________________________________________________‎ ‎【参考答案】was改成were ‎【知识讲解】‎ ‎ 集合名词,也叫集体名词,是英语中表示某一群人或某一类物的集合体。有时候看上去是单数,但其实是复数。当它作主语时,谓语要根据情况来判定到底是单数还是复数,确保主谓一致才行。 具体说来有以下情况:‎ 一、某些有生命的集合名词(表示人或者动物),本身有单、复数之分。‎ 其为单数时,若作主语,则谓语可用单数和复数形式。主要依据说话者强调的重点而定,若强调许多个体,谓语用复数;若强调一个整体,则谓语用单数。其为复数时,不言而喻,谓语必须用复数。‎ ‎※注意:此类名词单复数的意义并不完全相同,译为汉语时一定要当心,如army(一国之军队),armies(多国部队);couple(一对夫妇),couples(多对夫妇)等。‎ 常见的此类集合名词有:army,association,audience,band,board,cast,class,club,college,committee,company,community,congregation(教民,会众),council(市议会,理事会),couple,crew,crowd,enemy,family,firm,flock,folk,government,group,kingdom,mob(暴民,暴徒),navy,opposition,orchestra,pack,pair,party,personnel,profession,‎ population,staff,school,team,tribe(部落,部民),union,university等。 ‎ ‎【注】有时没有特定的上下文,谓语单数或复数区别不大。‎ ‎☛The public are [is] requested not to leave litter in the park. 要求公众在公园不要乱扔东西。‎ 二、某些有生命的集合名词,本身无复数形式,作主语时,谓语通常用复数。‎ 这类集合名词本身就表达出"一群人或其他"的含义,所以谓语常用复数。‎ 常见的此类集合名词有: cattle,clergy,faculty(教职工), herd,mankind,military,militia(民团、民兵),people,police,poultry(家禽),swine(猪),womankind等。 ‎ ‎【注】people作"民族"讲时有复数形式。‎ ‎☛There are 56 peoples in China.‎ 中国有56个民族。‎ 三、某些有生命的集合名词,本身无复数形式,其后可跟单/复数谓语动词。‎ 常见的此类集合名词有:bourgeoisie(资产阶级),church,elite(精英),gentry,intelligentsia(知识分子),laity(外行),livestock,majority,minority,proletariat(无产阶级),offspring等。 ‎ ‎【注】youth除了作集合名词以外,还可以作可数和不可数名词。‎ ‎☛Youth is the time for action; age is the time for repose.‎ 年少要动,年老要静。‎ ‎☛Some youths don’t like jazz.‎ 一些年轻人不喜欢爵士音乐。‎ 四、某些表示国家、公司、机构、运动队等名称的专有名词也可当作集合名词使用,其后通常跟单/复数谓语动词。‎ 机构、队伍等名称作主语时,谓语需要根据语境来判定——如果强调其作为一个整体,则用单数形式;如果强调其中的多个个体,则用复数形式。‎ 常见的此类集合名词有:Arsenal,BBC,Congress,Liverpool,Netherlands,Parliament,Pentagon,Vatican(梵蒂冈),White House等。 ‎ 这是个很清楚的例子,第一句强调的是作为一个队伍的整体,第二句则强调队伍里的每个球员,所以第一句谓语是单数,而第二句谓语是复数。‎ 五、某些含义上是集合名词,但实际本身就是不可数名词(表示物)通常被看成不可数名词,作主语时谓语用单数。‎ 常见的此类集合名词有:aircraft,baggage, clothing,crockery,cutlery(刀剪,餐具),equipment,foliage(树叶),furniture,glassware,hardware,jewellery,luggage,machinery,poetry,pottery,silverware,stationery(文具),underclothing,underwear,vegetation等。‎ ‎5. (2017·天津) Nowadays, cycling, along with jogging and swimming, ___________ as one of the best all-round forms of exercise.‎ A. regard B. is regarded C. are regarded D. regards ‎【参考答案】B ‎【试题解析】句意:现在骑自行车、慢跑和游泳被认为是最全面的锻炼方式之一。根据动词短语regard...as… (把……看做……)和句意确定应该用被动语态,排除A和D;由介词短语along with连接的三个名词作主语,谓语动词应该就前一致,即用单数,排除C。故选B。‎ ‎【特别注意】关于主谓一致:‎ ‎1. 当用作主语的成分后面跟由but,except,besides,including,like,with,as well as,along with,in addition to,combined with,rather than,together with等引出的短语时,谓语动词不受修饰成分的影响,习惯上要与这些结构前面的主语保持一致(即与比较远的那个主语保持一致,简称"就远原则")。‎ ‎☛Tom as well as his parents goes to the park every Sunday.‎ 汤姆和他的父母每个星期天都去公园。‎ ‎2. 不定式(短语)、动名词(短语) 或从句作主语时,谓语动词用单数。‎ ‎☛Serving the people is my greatest happiness.‎ 为人民服务是我最大的幸福。‎ ‎3. 当用作主语的两个名词或代词由or, either...or...,neither...nor..., not only...but also...等连接时,谓语动词通常与邻近的名词或代词保持一致(即与比较近的那个主语保持一致,简称"就近原则")。‎ ‎☛Neither the students nor the teacher knows anything about it.‎ 学生和老师都不知道这事。‎ 要点二:动名词作主语 ‎1. (2016·新课标全国卷II) Leaving the less important things until tomorrow (be) often acceptable.‎ ‎【参考答案】is ‎2. (2015·安徽) ___________ the difference between the two research findings will be one of the worst mistakes you make.‎ A. Ignore B. Ignoring C. Ignored D. Having ignored ‎【参考答案】B ‎【试题解析】句意:忽视这两项研究结果的差异将会是你所犯的最严重的错误之一。句子缺少主语,ignore的逻辑主语是you,两者是主动关系,且此处不表示完成,因此用动名词的一般式作主语,故选B。‎ ‎【知识讲解】‎ 一、概念 动名词由"动词原形+ing"构成。英语动名词是非谓动词的一种形式。从形式上,是在动词原形的末尾加上-ing,否定形式为not doing。它既有动词的特征,又有名词的特征,故称动名词。它也有时态和语态的变化,如表所示。但要注意:不及物动词没有语态的变化。‎ 形式 主动语态 被动语态 一般式 doin being do e 完成式 having done having been done 二、动名词的特点 ‎1. 它是从动词变化而来的,所以它保留了动词的某些特征,例如它能带自己的宾语、状语等,这时就叫动名词短语;‎ ‎2. 顾名思义,动名词最大的特点是它相当于一个名词,因此,动名词可以在句中作主语、宾语、表语、同位语等。因为它作为名词来使用,所以动名词也有像名词一样的所有格形式。‎ 三、动名词的用法 一、作主语 ‎ ‎1. 表示经常的、习惯性的动作或状态,谓语动词通常用单数。‎ ‎☛Walking is a good form of exercise for both the young and the old.‎ 无论对年轻人和老年人来讲,走路都是一种很好的锻炼方式。‎ ‎☛Watching news on TV has become a routine for me.‎ 在电视上看新闻已经成了我的一种日常习惯。‎ ‎☛Asking a woman’s age is impolite in our country.‎ 在我们国家,问一个女人的年龄是不礼貌的。 ‎ ‎2. 作主语时常后置,此时须用it作形式主语,用形容词或名词(短语)作表语。‎ 常用此种情况的形容词有dangerous, worthwhile, useless等;名词或名词短语有no use, no good, fun, hard work, a hard / difficult job, a waste of time 等。‎ ‎☛It’s dangerous swimming in the sea on windy days.‎ 有风的天气在海里游泳是危险的。‎ ‎☛It’s no use making an excuse for this.‎ 为这件事找借口是没有用的。‎ ‎☛It’s a waste of time talking about such a useless thing.‎ 谈论这样无用的事情简直是浪费时间。‎ ‎3. (2014·湖南) ___________ your own needs and styles of communication is as important as learning to convey your affection and emotions.‎ A. Understanding B. To be understood C. Being understood D. Having understood ‎【参考答案】A 注意:‎ ‎1. 动名词作主语时表示单数概念,谓语动词用单数形式。‎ ‎☛Walking after supper is good for your health.‎ 饭后走走路有益健康。‎ ‎2. 动名词的复合结构( sb’s doing)作主语 动名词的复合结构是指物主代词、名词所有格是动名词逻辑上的主语;动名词是其逻辑上的谓语。作主语时,谓语动词用单数形式。‎ ‎☛Your coming made us happy.‎ 你的到来让我们很高兴。‎ ‎☛Your father’s cooking is very good.‎ 你爸爸做的饭很好吃。‎ ‎3. 动名词与不定式作主语时的比较:动名词表示的动作通常是一个泛指的动作;不定式则通常表示具体的动作。‎ ‎☛As a child, she felt that visiting sick people was a duty and a pleasure.‎ 作为一个孩子,她认为去看望病人是一种责任,也是一件乐事。‎ ‎☛Being a guest in an American home will be a good experience for me.‎ 去美国人家里做客对我来说是一次很好的经历。‎ ‎☛To go on like this is useless. (=It is useless to go on like this.)‎ 继续这样下去是没有用的。‎ 要点三:动名词作宾语 ‎1. (2017·新课标全国卷I) Fast food is (be) full of fat and salt; by (eat) more fast food people will get more salt and fat than they need in their diet.‎ ‎【参考答案】eating ‎2. (2017·新课标全国卷II) This included digging up the road, ___________(lay) the track and then building a strong roof over the top.‎ ‎【参考答案】laying ‎【试题解析】考查动词,这里是由and连接的三个动词-ing形式,故填laying。‎ ‎3. (2017·新课标全国卷III)But unlike her school friends, 16-year-old Sarah is not spending half-term ____________ (rest). ‎ ‎【参考答案】resting ‎【试题解析】考查非谓语动词。固定短语:spend time doing sth. 花费时间做某事。‎ ‎4. (2016·新课标全国卷I) My ambassadorial duties will include ___________(introduce) British visitors to the 120-plus pandas at Chengdu and others at a research centre in the misty mountains of Bifengxia.‎ ‎【参考答案】introducing ‎【试题解析】考查动名词。介词后面应该用动名词形式作宾语。‎ ‎5. (2014·辽宁) Keep (hold) your position for a while.‎ ‎【参考答案】holding ‎【试题解析】考查动名词。句意:保持这个姿势一段时间。keep后面接动名词holding。‎ ‎6. (2016·新课标全国卷II) We can chose between staying at home and take a trip.(改错)‎ ‎_________________________________________________________________________________________‎ ‎【参考答案】take→taking ‎【试题解析】考查并列结构。本句中动名词短语staying at home与taking a trip构成并列关系,都是介词between的宾语。‎ ‎【知识讲解】‎ ‎1. 只能接动名词作宾语的动词,常见的有avoid, consider, enjoy, keep, finish, suggest, dislike, delay, escape, cannot help, imagine, mind, miss, practise, cannot stand, excuse, fancy, give up, put off, risk, insist on, look forward, feel like等。‎ ‎☛Have you considered looking for one friend?‎ 你是否考虑过找一位朋友?‎ ‎☛We must try to avoid repeating the same mistake.‎ 我们必须设法避免犯同样的错误。 ‎ 注意:‎ 当need, want, require, worth后面接动词-ing也可以表示被动(主动形式表示被动意义)。‎ ‎☛Your hair wants cutting.‎ 你该剪头发了。‎ ‎☛That novel is not worth reading.‎ 那本小说不值得读。‎ ‎2. 既可接动名词又可接不定式作宾语的动词,常见的有begin, start, stop, continue, like, love, prefer, by, mean, forget,remember, hate等。‎ ‎(1)在 like, love, hate, prefer等动词之后,用-ing或不定式意义上没有什么不同,只是侧重点有些不同,动名词表示泛指的动作,不定式表示具体的一次性动作。‎ ‎(2)在 begin/start, continue之后, 用动名词和不定式意义无甚区别,尤其是当主语是人 的时候。 ‎ ‎(3)在动词forget, remember, regret之后,用动名词与不定式意义不同:动名词表示动作先于谓语发生,不定式表示动作后于谓语动作发生。‎ ‎☛I remember posting the letter.‎ 我记得我已把信寄了。‎ ‎☛I’ll remember to post the letter.‎ 我会记着去寄信的。‎ ‎ (4)在try, mean之后,用动名词与不定式意义各不相同,如 try to do (设法做某事),try doing (尝试做某事),mean to do (打算/有意要做某事),mean doing (意思是/意味着做某事)。‎ ‎☛We must try to get everything done in time.‎ 我们必须设法及时把一切做好。 ‎ ‎☛Let’ s try doing the working in some other way.‎ 我们用别的方法做这工作试试。‎ ‎ (5)在go on之后,用动名词与不定式意义不同:go on doing 继续做一直在做的事;go on to do 接着做另一件事。‎ ‎☛Please go on doing the same exercise.‎ 请接着做这同一个练习。‎ ‎☛Please go on to do the other exercise.‎ 请做另外一个练习。‎ ‎(6)在stop之后,用动名词与不定式意义不同:stop doing 停止正在做的事;stop to do停下正在做的事去做另一件事。‎ ‎☛We stopped talking.‎ 我们停止了交谈。‎ ‎☛We stopped to talk.‎ 我们停了下来去谈话。‎ ‎3. 作介词宾语 ‎☛We’ve got to think of ways of changing people’s habits.‎ 我们得想些法子改变人们的习惯。‎ ‎☛After being away for several years, it is a strange experience to return to the hometown.‎ 离开几年之后再回到家乡,感觉有点怪。‎ ‎☛I insist on taking enough food for this trip.‎ 我坚持为这次出行带足食物。‎ ‎☛She was very interested in working for our company.‎ 她对为我们公司工作很感兴趣。‎ ‎★下列短语中的to都是介词,所以后面跟名词或动名词。如devote…to, object to, pay attention to, get down to, lead to, look forward to, stick to, be used to等。‎ 要点四:v-ing形式作定语 ‎1. (2017·北京) The national park has a large collection of wildlife, _____________ from butterflies to elephants. ‎ A. ranging B. range C. to range D. ranged ‎ ‎【参考答案】A ‎【试题解析】句意:国家公园有许多的野生动物,包括从蝴蝶到大象等等。此处野生动物和range之间是主动关系,用现在分词作定语,故选A。‎ ‎2.

(2015·北京)___________the early flight, we ordered a taxi in advance and got up very early.‎ A. Catching B. Caught C. To catch D. Catch ‎【参考答案】C ‎【特别注意】‎ 不一样的结果状语 现在分词作结果状语,是随着谓语动词的发生而产生的自然结果,其逻辑主语往往是前面整个句子所描述的情况,前面有时候可以加thus。而不定式作结果状语时常表示出乎意料的结果,有时前面可以加only。‎ ‎【拓展延伸】动词-ing形式作状语的注意事项:‎ ‎1. 动词-ing形式的时态 动词ing(短语)作状语时,要注意它的时间性,即注意是用其一般式(doing)还是用完成式(having done)。‎ 当动词ing形式的动作与谓语动词的动作同时发生或几乎同时发生时,用一般式。当它的动作先发生,而谓语动词的动作后发生时,用完成式。‎ ‎☛Walking in the street, I met an old friend of mine. 我正在大街上行走时,遇到了一位老朋友。(walking和谓语动词met同时发生)‎ ‎☛Having finished the letter, he went to post it. 他写完信后就把它寄了出去。(having finished是先发生的,went是后发生的。)‎ ‎2. 动词ing形式的否定式 动词ing形式的否定式是在它的前面加not。‎ ‎☛Not seeing John, I asked where he was. 我看不见约翰,于是问他在什么地方。‎ ‎3. 动词-ing形式的语态 使用动词-ing形式的主动式还是被动式,这主要取决于现在分词和句子主语间的关系。句子的主语就是分词的逻辑主语。‎ ‎☛Having been shown around the factory, they were very happy.(they是被带领着参观) 被领着参观了工厂后,他们很高兴。‎ ‎4. 动词ing形式作评注性状语 有少数动词ing(短语)并不表示主语的动作,即不存在其逻辑主语必须和句子主语一致的问题,只是表示说话人的态度。常这样用的有:‎ generally/frankly/properly/...speaking一般/坦白/恰当……说来 judging from/by...从……判断 considering...考虑到……‎ supposing...假设……‎ 要点六:构词法 ‎1. (2017·新课标全国卷I)However, be (care) not to go to extremes. ‎ ‎【参考答案】careful ‎【试题解析】考查形容词。句意:然而,注意不要走极端。分析语境可知be后面应该用形容词作表语,故填careful。‎ ‎2.

The central London Railway was one of the most (2) (success) of these new lines, and was opened in 1900. ‎ ‎【参考答案】(1)introduction (2)successful ‎【试题解析】‎ ‎(1)考查词性转换。空格前是the,后面应该是名词,故填名词introduction。‎ ‎(2)考查形容词。空格前是most,其后要跟形容词构成最高级,故填successful。‎ ‎4. (2016·新课标全国卷II) Then, handle the most important tasks first so you’ll feel a real sense of ___________ (achieve).‎ ‎【参考答案】achievement ‎【试题解析】考查名词。横线前面有介词of,横线上要使用名词作为of的宾语。所给词是动词achieve,其名词形式是加后缀构成achievement。句意:那么首先处理最重要的事情,那么你会有成就感。‎ ‎5.

(2017·新课标全国卷I)It was a relief and I came to a suddenly stop just in the middle on the road.‎ ‎____________________________________________________________________________‎ ‎【参考答案】(1)suddenly→sudden (2)on改为of ‎【试题解析】‎ ‎(1)考查形容词。句意:我来了个紧急刹车。suddenly是副词,表示"意外地,忽然地"。sudden为形容词,表示"突然的;迅速的",修饰名词stop用形容词,故将suddenly改为sudden。a sudden stop表示"急刹车"。‎ ‎(2)考查介词。分析语境可知此处表示"在路中间急刹车",on the road表示"在路上",the middle of the road表示"路的中央",强调的是"the middle",故将on改为of。‎ ‎【知识讲解】‎ 在英语中,词的构成方法主要有三种:合成、转化和派生。‎ 一、合成 合成词是由两个或两个以上的词合成一个新词的构词方式(有的合成词写在一起,有的中间需加连字符,有的是分开写的两个)。合成词的词义可以根据各个组成部分的意思加以推断。构成合成词的几个词可以是词性相同的词,也可以是词性不同的词。高中阶段常见的合成形式有:‎ 合成名词 notebook 笔记本 classroom 教室 blackboard 黑板 second language第二语言 合成形容词 lifelong 毕生的 secondhand 二手的 manmade 人工的 widespread 广泛的 合成动词 underline 画线标出 whitewash 粉饰 broadcast 广播 download 下载 二、转化 不增加任何成分,不改变词形,把一个单词由一种词性转化为另外一种词性的构词法叫转化法。高中阶段常见的转化形式有:‎ 名词→动词 button纽扣→button扣上纽扣 形容词→动词 correct正确的→correct改正 动词→名词 feed喂养→feed一餐;一顿 形容词→名词 native本地的→native本地人 副词→动词 up在上面→up提高 三、派生 派生,是英语主要的构词法。这方法是借前缀或后缀之助,制造出派生词,主要有名词、形容词和动词三种。前缀以否定前缀-im/-is等为主,使延伸出来的派生词变成反义词。‎ ‎(一)形容词加ly变为副词 ‎(二)动词/名词变形容词的后缀 ‎(三)动词变名词的后缀 ‎(四)形容词变名词的后缀 ‎(五)常表示人的后缀 ‎(六)表示否定或相反意义的前缀、后缀 ‎(七)构成动词的前缀、后缀
